Billing in stages means you send invoices during the project instead of waiting until all the work is done. Each invoice corresponds with completed work.
A lot of contractors wait until the end of the job and send one final invoice. But during that time, you might’ve already paid for materials, labor, fuel, and other job costs. All out of your own account.
That’s not great for your cash flow. In a survey of subcontractors, general contractors, and suppliers:
- 71% said they worry about cash flow.
- 30% said they use personal savings during cash shortages.
- 40% said they use half of all profits to fund day-to-day operations.
Progress invoicing for contractors can help to reduce some of that cash flow and payment strain. You collect money throughout the project rather than holding out until the very end.
In this guide, you’ll learn:
- Which jobs are a good fit for milestone payments
- How to create a staged billing schedule
- What to include in each progress invoice
- Common progress invoicing mistakes during long jobs
What Progress Invoicing Means for Contractors
Progress invoicing means you send invoices at agreed milestones during the project. This is instead of waiting until the job is completely finished to send a final invoice for the total amount. Each invoice is due after a specific phase of work. This allows you to get paid sooner for labor, materials, fuel, insurance, and other overhead expenses connected to the project.
With contractor progress invoicing, you don’t wait weeks to collect payment. Instead, you break the total cost down into milestone payments. Each payment is due after a completed phase or agreed-upon date.
A kitchen remodel might follow a schedule like this:
- 25% deposit before materials arrive
- 35% after demo and rough-ins
- 25% after cabinets and tile
- Final invoice after punch-list items
This approach gives homeowners more confidence during the project. They can connect each invoice to completed work inside the home.
That usually means fewer payment delays, fewer pricing disputes near the end, and less confusion about what was completed.
Jobs that are good fits for staged billing include:
- Kitchen and bathroom remodels
- Roofing jobs with several phases
- Large painting projects
- Landscaping and hardscaping work
- Flooring jobs that take more than a few days
- Any job with distinct phases
Some contractors also deal with retainage on larger projects, but that’s different from milestone billing.
The biggest benefit is faster access to cash. Your team still needs weekly pay, suppliers still expect payment, and fuel, disposal fees, software costs, and other overhead burden expenses still come out of your account while the project is underway.
Markup vs margin protection is another draw. A job might seem profitable while estimating. But over the course of the project, your business account starts to struggle. You can’t keep up with payroll, supplier invoices, and daily operating costs.
Progress invoices allow you to get paid sooner, so you can cover those costs.
Why Waiting Until the End of the Job Can Hurt Your Cash Flow
Waiting until the job ends to send an invoice can result in cash flow problems. Cash flow is the money coming into your business versus the money leaving it. During a long project, money usually leaves your account long before the client pays the final invoice. Progress invoices allow you to bring money in during the job instead of waiting until the end.
During a project, you have likely already paid for materials and delivery fees, team member wages, and fuel and travel time. All of that comes out of your account before the client pays a single invoice.
Then a homeowner asks for extra work midway through the project. You write up a change order and schedule extra labor hours before the client pays you for that added work.
Progress invoices let you collect during the job. You cover labor and materials from incoming payments instead of your own account.
Longer Jobs Create More Payment Risk
The longer a project lasts, the higher the payment risk becomes. More time creates more chances for weather delays, material backorders, labor overruns, or pricing questions.
Customer expectations can also change during long projects. A homeowner might agree to additional work during week two. Then they question extra charges on the final invoice.
That can lead to late payments, disagreements about changing orders, and frustration over the final balance.
Homeowners also tend to respond faster when each invoice covers one phase of work. The amount is smaller and the completed work is right in front of them.
Plus, you steer clear of the “busy but broke” cycle. You might have several active jobs and still run short on cash. Too much unpaid work tied up in ongoing projects will do that.

How to Set Up a Progress Invoicing Schedule That Makes Sense
A good progress invoicing schedule allows you to get paid before job costs surpass incoming payments. The best setup depends on project length, labor timing, and how homeowners expect to pay. The staged invoicing systems contractors use includes milestone payments, date-based invoices, and percentage billing.
Before choosing a billing schedule, compare how each method works.
| Billing Method | Best Job Type | Cash Flow Risk | Customer Friction |
| Milestone billing | Remodels and phased jobs | Lower risk due to more frequent payments | Lower because completed work is easier for homeowners to verify |
| Date-based billing | Long projects with ongoing labor | Medium risk during delays or slower weeks | Medium if visible progress changes slowly |
| Percentage complete | Complex remodels and additions | Medium risk if percentages confuse homeowners | Higher without written updates and photos |
Billing by Project Milestone
Milestone billing means invoices are due after specific phases of work are finished.
It works well for kitchen remodels, bathroom renovations, and roofing projects where each phase has a clear start and end.
Joist Payment Schedule lets you set payment timing upfront, so everyone is aligned before work begins.
Billing by Date or Time Period
Date-based billing means you send partial invoices on a set schedule, such as every two weeks or on the first of each month.
This works well when project timing changes during the job. Weather problems, inspection hold-ups, or supplier issues can throw off milestone schedules.
Painters, landscapers, and exterior service companies use this approach during projects with ongoing weekly labor costs, especially when labor burden shifts week by week.
Billing by Percentage Complete
Percentage billing means you send invoices after finishing a set portion of the project, such as 25%, 50%, and 75%. I
It fits larger remodels where several trades work at the same time and one phase might finish while another is still underway.
Percentage billing only works if you document progress clearly. Homeowners might question what “75% complete” actually means.
How to Explain the Schedule to Homeowners
The way you communicate your payment schedule affects how homeowners respond to invoices.
The way you communicate your payment schedule affects how homeowners respond to invoices. Before work begins, walk the homeowner through when each invoice is due, what it covers, and how change orders will affect the total.
Joist’s Custom Contracts feature gives homeowners clear written payment terms before work begins.

What to Include in a Progress Invoice
A progress invoice should explain exactly what work you completed, how much is due now, and what balance remains. When your clients can quickly scan their invoice and understand the charges, they usually pay faster and ask fewer billing questions. A detailed invoice also gives you written records for future pricing disputes.
Use these best practices to make each invoice easier for homeowners to review and approve.
List Completed Work in Plain Language
Avoid vague invoice lines. Instead, explain exactly what you completed during that billing phase.
For example:
- Removed old kitchen cabinets and countertops
- Installed rough-in plumbing for new sink layout
A few photos attached to the invoice give homeowners visual proof of completed work, too.
Using the Joist app, you can organize invoice items so homeowners can review completed work right from their phone.
Reference Earlier Payments and Remaining Balances
Your clients might ask why they’re being charged again or whether they have already paid for something. Anticipate those questions.
On each progress invoice, include:
- Original project total
- Deposit already paid
- Previous milestone payments
- Amount due now
- Remaining balance after payment
Handle Change Orders Right Away
If you never add change orders to the invoice, you lose profit on labor and materials you already paid for.
Instead:
Write up the change order and add labor and material costs as soon as the homeowner approves the work.
Attach updated pricing before extra work begins.
Include change order totals on the next progress invoice.
With Joist, updated invoices and change details are connected to the original job file.

The Best Way to Move From Estimate to Deposit to Progress Payments
When you establish payment terms on day one, collect the deposit, and send invoices during completed phases, you reduce billing confusion and get paid faster throughout the project. A simple workflow also cuts down on extra admin after long workdays.
Use this checklist to set up progress billing.
Step 1: Start With a Detailed Estimate and Payment Schedule
Your estimate should do more than list pricing. It should also include:
- Total project cost
- Deposit amount
- Payment milestones
- Due dates
- Change order process
- Final invoice timing
This gives homeowners a better picture of how you will bill them during the project. You won’t catch them off guard later with unexpected invoices.

Step 2: Collect the Deposit Before Work Begins
A deposit invoice gives you an upfront payment before you get going on the job.
Without a deposit, you might end up paying for materials, delivery fees, permit costs, and labor scheduling before the first payment arrives.
If you’re a roofer, you might collect 40% upfront before ordering shingles and scheduling labor. That money covers early job costs, so it doesn’t have to come out of your business account.
Joist makes it easy to request and track deposits before work begins.
Step 3: Send Each Progress Invoice on Time
If rough-ins finish on Friday, send the invoice on Friday. Waiting another week only delays incoming cash while labor and supplier expenses keep adding up.
Using Joist, you can send invoices right from your phone. It only takes a few minutes.
Step 4: Track Payments Without Extra Admin Work
You send an invoice. Then you wonder:
- Did they open it?
- Did they approve it?
- Which invoices are still unpaid?
This is where A/R aging becomes useful. A/R aging means tracking how long invoices remain unpaid after you send them.
If an invoice is left unpaid for too long, you might run short on cash while active jobs are still underway. The solution is automated invoice reminders.
Joist Payments gives homeowners flexible ways to pay each invoice stage. With payment reminders and notifications, Joist lets you track when homeowners open, view, sign, or pay invoices.

Mistakes Contractors Make With Progress Invoicing
Most staged billing problems start with poor communication or inconsistent invoicing. Homeowners get confused when you use vague milestones, leave extra work undocumented, or let invoices run late. Any one of those can turn a smooth job into a payment dispute at the end.
Common mistakes include:
- Using vague milestones like “phase two” instead of listing completed work
- Forgetting to update invoices after change orders or extra labor
- Leaving out payment processing fees when clients pay by card
- Waiting too long to send the next invoice after work is completed
- Changing the payment schedule midway through the project without written approval
- Sending a large final invoice after weeks without billing updates
Any one of these can turn a smooth job into a payment dispute. Catch them early and your final invoice becomes a formality, not a negotiation.
